Abstract: A drift kinetic model for the transport of non-maxwellian impurities is derived from first principles. This model fits in a consistent way in a hybrid concept, i.e. a combination of a fluid model for the background particles and a kinetic test particle description for the impurities. Impurities in a stationary toroidal magnetic field configuration are considered taking into account the interaction of the impurities with the background particles via Coulomb collisions. Also relevant processes like ionization, recombination and interactions with boundary materials in the tokamak are considered in the model. A Monte-Carlo-algorithm is presented for the numerical solution of the resulting model equations in realistic tokamak configurations. Results of simulations performed with the code DORIS for carbon and neon ünpurities in the tokamak TEXTOR are presented and discussed.
